So, I have a great many ton of ideas involving mostly reskins/classes through KSE, but is there anyway to actually make a mod out of KSE?
Lol, i feel so stupid xD Sorry if this isn't the right place to post, but if this is possible, I'd greatly appreciate help!

You want to be able to change appearances of the in-game characters? That is doable by editing the .utc of the character in question. Use KotOR Tool, and use the Creature Editor. Quite simple really

EDIT:

You will need to save the new creature and put it into your override. At the same time, you don't want to destroy the original characters unique template. So, make a copy of, say the p_zaalbar.utc, and rename it old_p_zaalbar.utc. Leave this unaltered version in your override if you like, or some other safe place. Then, edit the p_zaalbar.utc with the appearance you like, Alien_Gamorrean01, and save this edited version to your override. Now, when the game renders Zaalbar, it will use this edited version in your override and make it so Big Z is a big pig face.
